Press Release:

Sigma 18-200mm f/3.5-6.3 DC lens The Sigma Corporation are pleased to announce the launch of the new 18-200 f/3.5-6.3 DC lens. This high zoom ratio lens is exclusively designed for digital SLR cameras and capable of covering a wide range of focal lengths from wide-angle to telephoto. The built-in AF motor enables this lens to autofocus with all Nikon DSLR cameras. Two Special Low Dispersion (SLD) glass elements and two hybrid aspherical lenses offer the utmost correction for all types of aberrations, and enable this extended range super zoom lens to be housed in a compact and lightweight construction of 70mm (2.8in) diameter, and 75.6mm (3in) in length, and weighing just 395g/13.9oz. The new lens coating reduces flare and ghosting, which is a common problem with digital cameras and also creates an optimum colour balance. This lens has a minimum focusing distance of 45cm (17.7in) at all focal lengths and has maximum magnification of 1:4.4.

The lens design incorporates an inner focusing system, which prevents the front of the lens from rotating, making it particularly suitable for using circular polarising filters and petal shaped lens hoods. The overall length of the lens does not change during focusing, ensuring convenient handling and ease of use. A zoom lock switch eliminates zoom creep during transportation, a convenient addition when travelling.


  • Focal Length - 18-200mm
  • Minimum Aperture - f/22
  • Lens Construction - 15 Elements in 13 Groups
  • Angle of View - 69.3°- 7.1°
  • Number of Diaphragm Blades - 7pcs
  • Minimum Focusing Distance - 45cm (17.7in)
  • Maximum Magnification - 1:4.4
  • Filter Size - 62mm
  • Lens Hood - Petal Hood
  • Dimensions - Diameter 70mm (2.8in) x Length 75.6mm (3in)
  • Weight - 395gr/13.9oz
  • SRP - £329.99

The appearance and specifications are subject to change without notice.

Vignetting will occur if the lens is used with digital cameras with image sensors larger than APS-C size or 35mm SLR cameras.
